Question

a nuclear power plant is scheduled to undergo a retrofitting. what is the most likely outcome of the change?
the power plant will no longer generate radioactive wastes.
the power plant will recycle the water it uses to cool the reactor.
the power plant will be able to reprocess its used uranium fuel.
the power plant will switch from fission reactions to fusion reactions.

Explanation:

• Nuclear power plants always generate radioactive waste as long as they operate, so the first option is incorrect.
• Reprocessing used uranium fuel is a complex and not commonly done in most nuclear power plants (and retrofitting doesn't imply this as a standard outcome), so the third option is incorrect.
• Fusion reactions are not currently used in commercial nuclear power plants (and retrofitting a fission - based plant to fusion is far beyond current technology), so the fourth option is incorrect.
• Recycling water used for cooling (e.g., using a closed - loop cooling system instead of a once - through system) is a common and feasible retrofitting measure in nuclear power plants.

Answer:

The power plant will recycle the water it uses to cool the reactor.
